Vortex Flow Meter

  Application Vortex flow meter is used to meausre kinds of steam, gas, air and low viscosity liquid. Introduction According to Carmen and Strouhal relevant spiral produce and on the theory of the flow relationship. As shown in picture, In the meter body vertical insert a triangular prism root namely the happening of the body, when eddies of medium flow through the table body, in triangular prism behind the alternate produce in opposite directions regular karman swirl,its spiral separation and the flow of the medium frequency F speed by sensing head is proportional to the V detected the number of spiral,can measure the flow velocity,again according tp the table body mouth. Features Flange&body: integrally forged pieces, it will avoid break down into pieces. 100% SS304 material,we can provide material report. Circuit Board: Digital circuit board,anti most of the supplier use analog circuit board,digital circuit board enjoy the advantages of anti-vibration and anti-interference. Flow converter: Distinctive modular design, amateurs can operate, disassemble and assemble easily, it will avoid accident risks. Welding: adopt the advanced fish scale technology,which makes the welding seam looks nice and smooth. Japan OVAL technology with embedded-type sensor, triangular prism will not fall off, we already apply for patent. Our medium temperature sensor can measure highest temperature around 350℃,normal it is -40~250℃   Nominal diameter DN(mm) Liquid(t=20℃ ρo=1000Kg/m3) Gas(t=20℃ 101325 Pa Air) Standard Range Obtained Flow Range Standard Range Obtained Flow Range 20 1~8 0.6~12 5~50 5~60 25 1.5~12 0.8~16 8~80 8~120 40 2.5~30 1.5~40 20~200 18~300 50 3~50 2~60 30~300 30~500 65 5~80 3~90 50~500 50~900 80 8~120 5~150 80~1000 60~1200 100 12~200 6~240 100~1000 100~2000 125 20~300 13~390 150~1600 150~3000 150 30~400 15~600 250~2500 200~4000 200 40~800 30~1200 400~4000 350~8000 250 80~1200 40~1600 600~6000 500~12000 300 100~1800 1000~10000 1000~10000 600~18000 The size of stress type vortex sensor as follows: Table 1:Connection mode Connection mode Flange connection type Flange card installed type inserted type others Mark No 1 2 3 4 Table 2:Measured medium Measured medium Liquid common gas saturated stream superheated steam others Mark No 1 2 3 4 5 Table 3:Caliber Flange connection type,Flange card installed type Caliber 15 20 25 32 40 50 65 80 100 125 150 200 250 300 Mark No 150 200 250 320 400 500 650 800 101 125 151 201 251 301 Insreted type Caliber 100 125 150 200 250 300 350 400 500 600 700 800 900 1000 1200 1400 1600 1800 2000 Mark no 10 125 151 201 251 301 351 401 501 601 701 801 901 102 122 142 162 182 202 Table 4:special mark Format Common standard signal output Intrinsically safe explosion-proof Scene shows high temperature temperature compensation pressure compens ation Temperatu re-pressur e compens ation Mark No Mo mark M B X G W Y Z
